for automotive customers. AMSOIL carries over 700 WIX air, oil, fuel, racing and transmission filters for
automotive and light truck applications.
A History of Excellence
WIX is well-known around the world for its innovative filtration products for the automotive and light truck
market. Founded in 1939, the Gastonia, N.C., company earned acclaim during World War II when it created an oil
filter out of a paper tube, wooden plugs and yarn when steel was in short supply. In 1954 WIX created the
revolutionary spin-on oil filter that was eventually adopted as original equipment on most vehicles.
Today WIX manufactures some of the best oil, air, lube, cabin air, hydraulic, fuel, crank case breather and
transmission filtration products on the market. The company is also widely known for its support of NASCAR.
WIX oil filters have a full metal base plate for superior strength at the double seal. They also feature a silicone
anti-drainback valve that stays flexible in extreme temperatures. This improves oil flow and keeps oil in the
filter to prevent dry starts.
WIX oil filters use an up-front by-pass valve. This design is superior to top-mounted valves because it helps to
keep oil from washing past dirty media and entering the engine. The glass-enhanced media in WIX oil filters offers
greater efficiency, capturing more 10 to 12 micron sized particles than other cellulose/synthetic blend medias.
They also have a coil steel spring to ensure internal filter parts are sealed properly.
WIX panel element air filters have a linear path through the filter for low airflow restriction, a specially
formulated adhesive to form WIX’s exclusive pocket pleat for the filter media and a soft sealing urethane gasket
molded in place on the filter element.
Radial air filters are constructed of mesh screen on the inside wall diameter for element strength and media
protection from backfire. Each round filter is manufactured with heat-resistant plastisol with specially designed
crush seals on the top and bottom walls and adhesive seal joining the media ends. Additional Filtration Products
AMSOIL offers WIX filtration products for auto/light truck and racing applications. This includes not only standard
air and oil filters, but fuel, transmission, cabin air and filters specially designed for racing as well.
WIX fuel filters provide unmatched fuel cleansing performance. They prevent pump wear, injector clogging, premature
engine wear and help boost fuel efficiency. WIX fuel filters offer quick, easy filter replacement, long life and
the possibility of extended service intervals. WIX spin-on filters reduce the possibility of improperly installed
cover gaskets, and they provide effective, easy draining of excess water on filters equipped with the drain plug.
The superior materials, design and construction of WIX fuel filters provide excellent performance under all types
of operating conditions.
AMSOIL will also offer the full line of industry-leading WIX transmission filters for passenger cars and light
trucks. WIX transmission filters provide superior protection for many transmission applications in the auto/light

trucks. See Cabin Air Filter Installations (2MB PDF)
WIX filters are supplemental to AMSOIL Ea filters, but now AMSOIL will offers WIX filtration products that cross to
an Ea filter. With the exception of WIX lube filters, all WIX filters should be changed in accordance with original
equipment manufacturer’s (OEM) recommendations. WIX lube filter change intervals are extended OEM recommendations
to match the drain intervals of AMSOIL XL Motor oil. To find the correct filter for your application, consult the
Online Product Application Guide.
WIX Racing Filters
AMSOIL is carrying WIX racing filters in addition to filters for more common automotive and light truck
applications. WIX has been a part of racing and NASCAR for many years, both as a sponsor and in the race cars. The
company’s long-standing relationship with NASCAR not only demonstrates that WIX filters are high-quality products,
but it also shows WIX’s dedication to racing, making it a perfect match for AMSOIL.
Richard Petty began using WIX filters in 1967, winning six NASCAR championships with the help of WIX filtration
technology. Currently, WIX filters are used on more than 20 Sprint Cup cars, including those of two-time
champion Tony Stewart and 2007 Raybestos Rookie of the Year Juan Pablo Montoya. WIX is also an associate
sponsor of Joe Gibbs Racing and maintains a partnership with Toyota Racing Development (TRD).
WIX racing filters are specially designed for racing applications and are not intended for normal driving
applications. AMSOIL will carry all WIX racing filters, which includes 10 oil, 14 air and 2 fuel filters.
